Back in my day, only the wild, punky girls with dyed black hair and -- gasp! -- double-pierced ears! at my junior high wore blue nail polish. Oh the times, they have a-changed. Blue polish is totally mainstream and is, in fact, tres on trend. You can't throw a bottle of nail polish remover without hitting a celeb sporting a blue manicure.

Now, I'm all for wearing whatever darn color of nail polish you want, no matter how old you are! But, if you're feeling a little unsure about straying into the blue zone, I've got some starter steps you can take. With these looks, you'll be stylish and hip but feel like a grown-up person (versus the girl in detention coloring the ends of her hair with a black Sharpie).
